The most powerful cast iron kit after the pink Top performance for minarelli liquid scooter, it is a minacrom cast iron cylinder. It is the only one in its category which is cast in two segments with the black top to have 8 transfers, 6 of which are opposite and two are placed later to optimize the filling. The exhaust is normal and the mono segment piston is in reinforced alloy. It is relatively torquey, powerful and solid, it really has a great reputation already abroad because it can be expensive, very solid, clean, torquey, powerful, only good, some do up to 25,000 km with this type of kit by changing the piston every 10,000 without even reaming.
Peak level is also very impressive. You can also do a lot of km because it is very solid (it's the magic of minacrom cast iron) and you can rebore it at a lower cost in 47.4mm diameter (we have all the spare parts). Preparation possible on request. You can also place a liquid minarelli pink top piston on it which will allow you even more power and high speed because in mono segment, treatment and different alloy. You can also boost it with a two-part pink top cylinder head that can be installed without modifications on it. The combustion chamber of its cylinder head is in high compression studied and tapered but unfortunately not polished.
We recommend fitting at least with this kit: racing exhaust, cold racing spark plug, 17.5mm carburetor, reinforced bearings and crankshaft.
As an option we offer you a stage 1 preparation, this preparation is a modification of the channels and the exhaust port by increasing the diagrams and improving the duct, it increases the performance of the cylinder. An improvement of the piston and the lower skirts is also included in this modification. Count a little extra time for this preparation!
